20080266565 | Device and method for measuring ink levels in a container - An ink level sensing device and associated method. The ink level sensing device includes a near infrared illumination source that emits near infrared light, and a container configured to accommodate a supply of ink containing light absorption material. The device further includes a protruding chamber adjacent to the container. The protruding chamber is configured to accommodate a portion of the supply of ink accommodated by the container. The device also includes a sensor that is configured to receive a signal based on an amount of the light that passes through the protruding chamber. The method includes emitting a light from a near infrared illumination source and directing the light toward a protruding chamber of the ink supply. The method further includes sensing an amount of the light that passes through the protruding chamber in the ink supply. | 10-30-2008 |
20110157647 | Replaceable Printer Component Including Memory Storing Data Defined by Tags and Sub-Tags - A replaceable printer component includes a memory and a communication link. The memory is configured to store data in each of a plurality of portions of the memory. Each portion is defined by a tag. Within a first portion of the memory defined by a first tag, the data within the first portion is stored in a plurality of sub-portions of the first portion. Each sub-portion is defined by a sub-tag. The communication link is configured to communicatively link the memory to a printer controller when the replaceable printer component is installed in a printing system. | 06-30-2011 |

20140368565 | PROVIDING REPLACEMENT PRINTING FLUID TO A PRINTER - A method performed using a computer includes receiving a cumulative consumption value for a printing fluid corresponding to a supply from a printer at the computer. The method also includes calculating a plurality of variable values by way of the cumulative consumption value for the printing fluid, a statistically derived depletion quantity for the printing fluid, and an estimated time to ship a supply of replacement printing fluid to the printer to form calculated variable values. The method also includes causing the supply of replacement printing fluid to be shipped to the printer in accordance with the calculating. | 12-18-2014 |
20150127498 | PROVIDING REPLACEMENT TANGIBLE RESOURCE TO A DEVICE - Example implementations relate to tangible resources. For example, a method includes receiving, at a computer, a cumulative consumption value of a tangible resource from a device that consumes the tangible resource. The method also includes calculating a plurality of variable values by way of the cumulative consumption value, a statistically derived depletion quantity of the tangible resource, and an estimated time to ship a supply of replacement tangible resource to the device to form calculated variable values such that the calculating is performed at least in part by the computer. The method further includes causing the supply of replacement tangible resource to be shipped to the device in accordance with the calculating. | 05-07-2015 |
20150355870 | MESSAGE OUTPUT BASED ON VALUE - A first, message is output the resource balance is less than or equal to the low value or the device total is greater than or equal to the very low value. A second message is output if the resource balance is less than or equal to the very low value or the device total is greater than or equal to the very low value. Use of the device or resource is stopped until a user acknowledges the second message. | 12-10-2015 |
20160034802 | SECURE UPGRADE SUPPLIES AND METHODS - Example secure upgrade supplies and methods are disclosed. A disclosed example upgrade supply cartridge structured includes a chamber to store a material useable by the imaging forming apparatus to form an image on media; a security device to provide an authentication credential to an image forming apparatus, the authentication credential useable to authenticate an identity of the upgrade supply cartridge; and a tamperproof data storage including upgrade data useable by the image forming apparatus to activate a capability included but disabled in the image forming apparatus, the tamperproof data storage structured to store an identifier of the image forming apparatus after the upgrade supply cartridge has been utilized by the image forming apparatus to activate the disabled capability. | 02-04-2016 |
